This paper reviews recent advances and trends in the use of edible coatings as a safe alternative to preserve and extend avocado shelf-life. Edible biopolymer coatings have gained considerable attention due to their ability to extend fruit and vegetable shelf-life, with nonactive coatings forming a physical barrier and active coatings containing supplementary ingredients with additional properties like antioxidant and antifungal activity.
Avocados (Persea americana) are a fruit, whose shelf-life is jeopardized by rapid ripening and fungal diseases, which heighten the necessity for postharvest treatments. The use of refrigeration during storage and transport helps delay the ripening process and phytopathogen growth but it is not enough to attenuate the problem, especially once avocados are placed in ambient temperatures. Fungicides are effective in controlling fungal prevalence, but their possible adverse environmental and human health effects have spurred interest in finding safer, natural substitutes. The objective of this paper is to review recent advances and trends in the use of edible coatings as a safe alternative to preserve and extend avocados shelf-life. Edible biopolymer coatings have gained considerable attention due to their ability to extend fruit and vegetable shelf-life. These coatings are a novel type of biodegradable primary packaging made from biological compounds like polysaccharides, proteins, lipids, and other polymers. Coatings are considered nonactive if they only form a physical barrier, separating avocados from their immediate environment, controlling gas and moisture transfer. Active coatings can contain supplementary ingredients with additional properties like antioxidant and antifungal activity. The application of edible coatings shows promising potential in extending avocado shelf-life, replacing synthetic fungicides and reducing economic losses from avocado spoilage.
